Acids are popular in skincare for a reason—they deliver real results. Two standout ingredients are azelaic acid and salicylic acid, both loved for their ability to clear skin and even out tone. But they work in different ways and target different concerns. Here’s what you need to know to choose the right one for your skin.
What is Salicylic Acid?
Salicylic acid is a beta hydroxy acid (BHA) that is oil-soluble, meaning it can penetrate deep into pores to dissolve sebum, dirt, and dead skin cells. Best For:
-
Acne and blackheads
-
Oily, congested skin
-
Exfoliating and unclogging pores How It Works:
-
Breaks down the bonds between skin cells
-
Clears out pores and reduces oil buildup
-
Helps prevent and treat breakouts Skoah Picks:
-
Charcoal Kleanser – Combines salicylic acid and charcoal for a deep pore-cleansing experience
-
Turbo Tonik – Uses malic and oleanolic acid to help control oil and bacteria (contains similar benefits to BHA)
What is Azelaic Acid?
Azelaic acid is a lesser-known multitasker with major benefits. It’s derived from grains like barley and wheat and has antibacterial, anti-inflammatory, and brightening properties. Best For:
-
Redness and rosacea-prone skin
-
Uneven skin tone and pigmentation
-
Texture concerns and post-acne marks How It Works:
-
Reduces inflammation and bacteria
-
Gently exfoliates to improve tone and texture
-
Inhibits melanin production to fade dark spots

Can You Use Azelaic and Salicylic Acid Together?
You can—but with caution. Both acids exfoliate, and layering them can be too harsh, especially for sensitive or compromised skin. Tips:
-
Use one in your morning routine and one at night
-
Alternate days between acids
-
Always follow with soothing ingredients like hyaluronic acid, niacinamide, or a calming moisturizer
-
Don’t forget SPF during the day
Soothing Ingredients to Layer With Acids
Pair your exfoliants with barrier-supportive ingredients to prevent irritation:

+Niacinamide – Helps calm inflammation and visibly reduce pores

Both azelaic acid and salicylic acid are incredible tools for clearer, smoother skin. The best choice comes down to your skin's unique needs: go with salicylic for clogged pores and oil, and azelaic for tone, texture, and redness. With mindful use and supportive products, you can build an effective, skin-friendly routine that brings out your natural glow.
